Natural Irony
It's only 'irony' if your hypothesis, that man-made heat and environmental pollutants are the ONLY causes of Arctic and Antartic ice melting, is correct!
You, like most of the "global-warming", (AKA "The sky is falling, the SKY is fallling!") nuts, are totally disregarding the FACT that the ice has melted and re-frozen several times, with absolutely NO HELP from mankind! Many of the so-called 'pollutants' being blamed are, in fact, produced by the earth naturally, such as by volcanoes, at the edges of those plate techtonics (pardon my spelling efforts)!
